Just make sure you don't shoot yourself in the foot by telling the best route to the end of the tunnel is via the tunnel itself...

The point of the GRE tunnel is to allow me to establish a BGP session to another AS using a consumer grade Internet connection (cheap) over the public Internet. I don't want to build out additional microwave paths to a new datacenter to become multihomed. On Fri, Jan 28, 2011 at 5:36 PM, C. Jon Larsen <jlarsen@richweb.com> wrote:
I have read your email a few times and i dont see how this makes sense.
Why do you need a public AS and PI space? Your gre tunnel wont need it or be able to use it. A gre tunnel is just a replacement for a physical pipe.
If your datacenter based presence goes down, you will need a pipe at your office, or some other location speaking bgp that can annouce your block anyway.
